Packet Dump Decode (pdd) is a simple, convenient GUI wrapper around the Wireshark/Ethereal tools to convert packet hexdumps into XML containing the decoded protocols and protocol contents. Using pdd, you just need to copy-paste the hexdump into pdd and hit the "Decode" button.

Suriwire is a plugin for Wireshark that displays Suricata generated alerts for a pcap file inside the Wireshark output. It adds the alerts to the packet details and in the expert info window. It also enables you to use signature fields as filtering items in Wireshark output.

pcapfix is a repair tool for corrupted pcap and pcapng files. It checks for an intact pcap global header and packet block and repairs it if there are any corrupted bytes. If a header is not present, one is created and added to the beginning of the file. It then tries to find pcap packet headers or packet blocks, and checks and repairs them.
